Answer Posted / karan am
surrogate key is alternate to primary key, in order to maintain historical data.
The key source can be a state file or a database sequence. If you are using a database sequence, the sequence must be created by the Surrogate Key stage. You cannot use a sequence previously created outside of DataStage.
